ToaZZ'wwm t may concern.-

Be it known that I, IRVINE C. BEATTY, of Merchantville, Camden county,New Jersey, have invented an Improvement in Looms, of

which the following is a specification.

Myinvention has reference to looms; and it consists of certainimprovements, all of which are fully set forth in the followingspecificathe warps.

The particular construction of my lettingo or tension device for thesevarious warpthreads is fully described hereinafter when referring to thedrawings.

A second part of my invention consists in devices for bringing thevarious wai-ps from the heddles in separate layers over the top of theloom and by suitable guide-rods or rollers to the tension or letting-oftdevices and locating such tension or letting-oft devices in the front orback ot the loom, but separated from it sutciently to enable theoperator to pass between the loom proper and the up- `wardly-ertendin gwarp-threads and their tension or letting-oft devices. This enables theoperator to watch the weaving of the various webs and at the same timeby simply turning his head to have in full view every warpthread whichis-being fed to the loom, thereby being enabled to observe and inposition to overcome any defect which might exist by the breaking of awarp-thread long before the end of said broken warp-thread passesthrough the heddle.

lVhile my invention is particularly adapted tolooms forweavinga seriesof separate webs when all are controlled from the same power mechanism,it is also applicable to any type of loom in which two or more sets ofheddles are employed.

In the drawings, Figure l is a sectional elevation of aloom and thetension or letting-off devices embodying my invention. Fig. 2 is aperspective view of one of the letting-ott or 'of the tension orletting-off devices.

tension devices. Fig. 3 is a front view showing two of the guide-rollersof a pairof tension devices, illustrating how the weights of the upperroller may pass below the level of the lower tension-roller; and Fig. 4is a perspective view of one of the brake-frames for carrying thetension-roller and guide-roller, showing the use of vertical guides forthe tension-roller.

A represents the loom proper, which is provided with the usual reed andlathe and the heddles B,`of which there may be any desired number. Tothe rear of the heddles are Aarranged a series of bars, guides, or rodsC, preferably o ne for each series of warps. Ar-

ranged to the upper part of the loom over the rods C are a similarseries ot rods or lguides D, and again in front of the` machineand abovewhere the operator would pass in attending theloom is a third series of'such bars or guides E. The bars or guidesD andEare arranged obliquely,so as to keep the various layers of warp-threads separated as far aspracticable.

In the front of the machine is arranged the tension or letting-oftdevices F, which are located one above the other and so positioned withrespect to the loom proper that a passage-way P is formed for theoperator, whereby he may either attend the loom A or examine thevariouswarps passing over the spools If the tension devices are located in thefront of the loom, .then-the passage-way Pis arranged-beltween the latheportion of the loom and the sage-way P would be arranged between "thleheddles and the tension devices. In'either case there is a passage-Wayupon both's'i'des f a bobbiu or spool G, journaled in an uprightl frameH and carrying the Warps for one of IOO ICI

the heddles, and a frame I, pivoted below said spool at J, in which isjournaled or supported aroller or guide-rod L. Tension-cords K passaround the flanges g of the spool G, one end of which cords is fixed tothe frame H by being connected to the pivot J, and the other end ofwhich cord is connected to the frame I at a distance from itspivotorfulcrumpoint J. It will be seen that anytendency to press down thefreeend of the frame I will cau-se a tension to be exerted by the cordsor bands K upon the spool or bobbin G and prevent its unwinding, andvice versa. The warpthreads pass from the spool G over the guide rod orroller L and under a roller or guide M, which is vweighted at each endby weights N. From under said roller or .guide M the said `warps passupward to the guide-rods E, thence to guide-rods D,thence downward underthe guide-rods lC to the lleddles. The axles of the guide-rollers M maybe guided invertical guides t' on the frame I, said guides being clearlyshown in Fig. 4. Such guides prevent any lateral swaying of theguideroller. However, if desired, these guides may be dispensed with. Asthe loom .takes up the warp-threadS .the guide rod or roller is lifteduntil it lifts the frame I, releasing the tension on the spool G, whichaction allows ,the weighted roller or guide M to pull down gradually,causing the vspool -G to let o fa cert-ain amount of the warp-threads.

As soon as the roller or guide M falls the ,downward pressure of vthewarp-threads on the roller L forces down the `frame I and arrestsfurther movement of the spool `G. During ythe further action of the loomthe warp which is taken up in the manufacture of the fabric draws uponthat portion of the warp in which the roller or guide M iS suspended andgradually lifts said roller or guide M 'and its weights N until it againlifts the frame I and repeats the operation of letting oit the givenamount of warp, as before. There is a series of these tension and let,-`ting-.off devices arranged one above the other in the frame F, asindicated in Fig. l, and thel guide rods or rollers E are arrangedslightly at an angle to the loom, so that the various layers ofwarp-threads rise upwardly and at i fulcrufmrpeint J. A convenientmethod is to .of the same size, the next two larger, but of the samesize, and so on-thus enabling the' rollers L and M to be carried fartherout to insure a more ready guidance of the warp to the guide-rods E anda clearance of the tension-weights. This difference in the size of theframes [is clearlyshown in dotted lines in Fig. l. Where the verticalspace is limited for any given number of spools G, it is desirable tomake the axle of the upper tensionroller M of a pair longer, so that theweights N, suspended therefrom, may descend outside of the weights N ofthe roller M immediately below, as is shown in Fig. 3. The weight N ofthe next pair above being located nearer to the spool G, they coulddescend without coming into contact with the weights below. By thisconstruction a maximum 'vertical movement of the roller M may be hadwith the limited vertical space in which the spools rG are located.

By my vimprovement l am enabled to Vfeed the various threads in fiatlayers, so that there is no tendency whatever for tangling or knottingof the various threads making up the fabric, and yeach :and every threadcan be readily observed by the operator at alltimes, .thus overcomingany Vcomplication which Ymight resultfroin defects'in the-threads whenfed to the loom in rope-like layers, as has been customary heretofore.

The construction of the loom may be such as is heretofore welll known,and may be varied -to suit the requirements of the manufacture of anyspecial kind of fabric. Gonsequentlyl do not limit myself `to thedetails thereof. Likewise the details of my improved tension device maybe moditied'without departing.

from the spirit of the invention, and I might add that, broadlyconsidered, it is'immaterial where the said tensiondevice is locatedwith respect to the loom; bu-tI prefer to locate it as shown, so as toform the passage-way for the operator between the spools the loomproper.
